Opinions/Ideas???

Thought I would do a road trip to Irvine Ca. from Vancouver Canada and pick up a bike I bought off the net. Made it to Calf OK but the rig was a little dirty. Had it washed and detailed. When I drove away the stabilty and check 4 wheel drive lights came up on the dash. I contacted Onstar and they confirmed the failures. I made an appoointment at a Hummer dealer in San Juan Capistrano to have it looked at. Later in the day I drove it and the fails were gone. Had Onstar check and they were gone.
Soooo....do I take the H3 in and have checked which might take 3 days? Or, do I just write it off to moisture and having the buttons on the dash wiped by the detailer???

What to do????
